Anyone else rocking thumb shifters on the drops?

I don't mean kelly's or anything like that, I mean good old fashioned thumb shifters mounted on the drops below the hoods. I'm about to go back out to finish cabling this conversion, but it occurred to me I never have seen any of you guys with it, or at least not that I can recall.. and no suntour commands don't count either, those things seem made for it! Pics please if you got'em!

It looks interesting... I'll be interested to know how that works out for you.

I've found a couple issues already but they really aren't big issues for me, for other people they may be deal breakers though. 1 Granny gear is hard to pop into at speed (Not an issue at all for me), second is because of the clamp bolts the tops of the drops are useable still but uncomfortable, however the SIS indexing dialed right into the 105 RD and 7 freewheel... and it shifts like a dream.. I've only caught myself once so far reaching down to try and use my DT shifters.. I will say though I did get lucky with the thumb lever length and how my hoods are positioned etc.. kinda a perfect storm in my favor it seems.

I mounted my thumb levers on the top next to the stem. ( the're on my dropbar mtb beater) Shifting up is a matter of bringing my hand off the hood and bumbing the lever back ( it's indexed ) down shifting? Who wants to go slower? Seriously, I just reach back with my thumb and pull it forward. Tried it your way and it did't work for me..... but your way looks cooler and that's worth something.

Are those the same shifters you tried on drop bars? And who cares about looks.. I put them where I did for functions sake, I spend 95% of the time on the hoods. The ones in the pic don't look like they'd make a good fit on the drops to me, but who knows? Do you mind if I ask what issues you had with the way mine are mounted, perhaps you can give me insight to something I'm not gonna see coming?

Yep same ones ( cables pointed down on a bracket I bent to fit under the brake . You can see I broke the right shifter case in the process of swithching them. ) . On the drops I could only use my thumbs and at the upper end of the shifters range I had a hard time getting my hand around the hood to pull the shifter back to down shift. The other issue is, it's my winter beater, so I ride with heavy gloves a lot of the time. With the shifters on the top, I can shift by bumping the shifter with the back of my hand instead of a frozen numb thumb. That was about it. I just found it worked for me better on the tops. Yours are mounted over the tape too, so moving them around won't be that big an issue. The negative with my set up is that the tops of the bar are now too crowded to use, but I ride the hoods or drops anyway so it really doesn't matter to me.

Ahh cool. Those shouldn't be any problem for me, this is my fair weather bike. :/

Why don't more people use thumbies instead of brifters is what I want to know now?

I guess cuz with brifters you can just fire away, thumbies are a bit slower.

Interesting (I'm test riding in between posts here), I've been playing with my rear shifter and I can make complete gear cluster dumps even in the SIS mode with one movement.. my understanding is brifters can't come close to that right?

No, your right, they can't. I was more thinking gear by gear, not the entire cluster!

Well I can also stop on any of those clicks! I thank you sir for you invaluable insights, but I can't help but wonder why we're the only two admitting to it atm.

yeah i've contemplated doing it for a drop bar mtb.. i think i would do it like velognome though and have them near the stem. looks like funky though. the shifters by the brakes definitely looks like would be uncomfortable to shift sometimes

thumb shifters rock.. got a new bike with trigger shifters and one side doesnt work... never had thumbies that didnt work

Like Velognone, I've put thumb shifters on drop bars next to the stem. I liked them there, but eventually decided that they took up too much space. I tried them at the ends of the drops, too, but decided that they were inferior to bar end shifters in that position. And I also did try them below the brake levers. Here I found that they interfered with my hands when I was braking from the hooks/drops. (Maybe they were mounted too low?) So, I gave it up for a bad job. If you can make it work, my hat's off to you!

Here's a thought: when you pull the turkey wings off a set of old Dia-Compes, you're left with a little alloy stud sticking out. Could a person mount a set of thumbies on those?

I'm thinking, why not...but I'm sure it would interfere with actually being able to grab and use the hoods.

I just don't see any positives to doing it. Ergonomically it looks to be far worse than STI/Ergos or bar ends - losing a comfortable/useable position in the drops doesn't make sense to me. More hand positions = better. Mounting them near the stem wouldn't work for me either. As noted, it takes up real estate that would better be suited for lights, a computer, or whatever. That said, whatever works for you is just fine by me

Day 2: Still loving it, and I'm going to see about some kind of wedge to slip right next to the clamp bolt and wrap it down, I think that should solve the problem with using the drops. Because of the positioning of the levers themselves, I haven't run into any issues with them being in my way, either from the hoods or the drops.

Der I feel you, I know it flat out isn't for some people. I however am enjoying have complete throws and being able to stop indexed on a gear.. it's great for me.

Cap'n I've thought about it myself.. but you need to look at where that nub is on the lever and remember your shifter would be right there! And more then likely it'd have to be a down tube shifter.. there's no way you can get that out of the way.

Strock, I wasn't kidding when I said mine just happens to be a perfect storm in how it worked out I utterly expected your results as my own.

and mr Gnome, I agree if they're mounted too high etc it could definitely make the hoods hard to reach, by the way mine are setup even when it's close to being in my way, my thumb rests easily against the shifter comfortably.

Campy Ergo 8's drop the whole cassette if I remember correctly (it's been 12 years).

Thumbies aren't in the same league even though I use them and like them.

C8 can drop the whole cassette. The newer ones can drop 5.
